BARREL AND LIKE CONTAINER.

Application filed December 12, 1925, Serial No. 74,995, and in GermanyOctober 17, 1925.

' My present invention relates to barrels, drums and like containers,generally made 'of' sheet iron, and particularlyto that type in whichthe cover or head projects into an annular inwardly open chamber, and isheld therein by suitable locking means such as an expanding ring. Saidannular chamber is formed in a ring having flanges at its ends 1 to.form an inwardly open groove. The 0bject of my present invention is toimprove the construction of containers of the type above mentioned,particularly for the purpose of obtaining tLSBClllG. support for theinner portion of the annular member which holds the cover or cap. Forthis purpose the'body of the container is provided with a transverselyextending portion or flange which engages and preferably embraces thelower or inner portion of said ring.

Two satisfactory and preferred embodiments of my invention areillustrated by the accompanying drawings, in which Fi 1 is a partiallongitudinal section of'a barrel or like container embodying myinvention; Fig. 2 is an end view thereof and Figs. 3

and 4 are partial longitudinal sections showing other forms of myinvention. According to Figs. 1 and 2 the body or shell (1 is ofcylindrical shape and is provided atits end (or at both ends) with aninwardly extending flange b and with a return bend 0 between which isreceived the lower or inner flange of a ring seat 9, said ring seat isalso provided with an n per or outer flange and between these two angesis thus formed an annular chamber orgroove open inwardly and adapted toreceive the edge of the cover d as well as the packing e and lockingmeans to hold the seat in place after insertion. Such locking means mayconsist of an expanding ring f which is of split construction and may becompressed so that it will pass through the opening in the top flange ofthe ring seat 9; when such ring is then released, it will expand intothe position shown so as to lock the cover in position. It will be seenthat the construction described and illustrated provides a securesupport for the inner flange of the ring seat g.

While in Fig. 1 the body or shell has an inward projection to form thesupport for the ring seat, reverse arrangement may also be adapted, forinstance, as shown in Fig. 3, where the annular support b is formed bybending the material of the body of outwardly and the ring seat g, inaddition to the two inwardly projection flanges of the same character asshown in Fig. 1, has an out: wardly projecting flange g", which isreceived between the outwardly bent portion 5' and an inwardly bentreturn portion a". The barrel shown in Fig. 3 is not cylindrical, buttapered towards the ends and is also shown as provided witlrlongitudinalcorrugations h, which, however, terminate at the outwardly bent portionb, the terminations of the corrugations forming, as clearly shown, astronger and more rigid support for the ring seat.

The constructionshown in Fig. 4 may be considered as a combination ofthe structures shown in Figs. 1 and 3, that is to say, in Fig. 4 thering scat g, which is the same as shown in Fig. 1, is connected to abilged barrel a having the longitudinally extending corrugations aformed therein similar to the barrel shown in Fig. 3. The annularsupport 6 however extends inwardly from the periphery, or along thelower face of the lower flange of the ring seat and the return bentportion 0 extends around the upper surface of said flange in a mannersimilar to the construction shown in Fig. 1.

The connection of the inner or lower portion of the ring seat 9 or gwith the annular support 6, bf or b is preferably accomplished by meansof the return bent portion 0, a or 0 but I do not wish to restrictmyself to this particular construction. and I desire it to be understoodthat the connection of these two parts might be etiected in other ways,for instance by riveting or welding.

It will ofcourse be understoodthat the diameter of the openingsurrounded at the outer flange of the ring seat 9 or g is sufficient toallow the cover (l to be inserted through said opening.

' Various changes in the specific form shown and described may be madewithout departing from the spirit of my invention.

I claim:

1. A container comprising an open ended cylindrical shell and a coversupporting ring seat at the open end thereof, sald' ring seat having aside wall, and an upper flange and a lower flange extending inwardly andlaterally from said side wall, the lowerflange being of greater widththan, and extending inwardly beyond said upper flange, and said shellhaving an integral laterally eirtending flange to provide a laterallyextending supporting surface conterminous' with said lower flange and incontactin engagement with the lower surface thereof, and said shellbeing further provided with a return bent portion extending about theedge and the upper surface of said lower flange for securing said ringdirectly to and in interlocked engagement with said shell.

- ment with said leg to connect said ring seat directly to the body ofthe container, whereby the side wall material only is employed toconnect the ring seat directly to the container and said flanges andsaid leg of the ring seat co-operate to reinforce the container at the 0en end and to form a rigid support for t e cover and cover closingmeans.

3. The combinaton with an open-ended container having sheet metal sidewalls, a cover and packing therefor, a ring seat of U- shaped crosssection, the side wall of said container being bent to form a pair offlanges extending transversely from said side wall in spacedrelationship to each other, and defining an open-ended groove into whichthe lower leg of the U-shaped ring seat is received, said flanges beingclamped tightly to said lower le to secure said ring seat directly tothe s eet metal of the container, the end of the side wall materialwhich forms the outer one of said flan es terminating within said ringseat on the ower leg thereof, and serving with said lower leg to form asupport for the gasket or packing interposed between the cover for thecontainer and said support, whereby said packing serves to preventleakage between the cover and ring seat and between said flanges andring seat.

4. A container comprising an open ended sheet metal shell and aone-piece cover supporting ring seat at the open end of said shell,characterized by the sheet metal material of said shell being bent, ashort distance from the end thereof, to provide a laterally extendingflange which forms a wide supporting surface against which the inner endsurface of said ring seat is su ported, the side wall of said shell immei-v terial of said shell being bent, a short distance from the endthereof, to provide a flange which extends at right angles to the axisof the container and forms a wide supporting surface a ainst which theinner end surface of said ring seat is supported, the side wall ofsaid'shell immediately adjacent to said flange being located within thelimiting circumference of said ring seat and forming a rigid bracingsupport for said ring seat and flange, and the terminal end of saidshell being bent around a laterally projectingflange of said ring seatto hold said ring seat and shell securely and rigidly in interlockedengagement.

(LA container comprisingan open ended sheet metal shell and. a one-piececover supportin ring seat at the o 11 end of said shell, c aracterizedby the s eet metal material ofsaid shell being bent, a short distancefrom the end thereof, to rovide' a laterally extending flange which ormsa wide supporting surface against which the inner end surface of saidring seat issupported, the

side wall of said shell immediately adjacent.

to said flange being located within the limitmy hand.
